  • Publication number: 20070048750
    Abstract: The present invention discloses a method for rapid assessment of lung cancer therapy efficacy in a few days instead of weeks by conventional imaging methods. This method can also be used to detect relapse of the cancer and to improve the current TNM cancer staging method for more accurate prognosis. The rapid assessment of therapy efficacy is based on detecting circulating cancer cells in body fluid with high positive detection rate. The high positive detection rate is achieved by using PCR amplification of multiple marker genes identified by in silico search of DNA sequence database. This invention also discloses a scoring method to calculate the cancer cell load based on PCR results to correlate the amount of circulating cancer cells in lung cancer patients with their treatment outcomes.

  • Patent number: 7167072
    Abstract: An inductor formed on a substrate having a dielectric layer thereon is disclosed. The inductor includes a first inductor pattern, a second inductor pattern a third inductor pattern. The first inductor pattern is formed within the dielectric layer, the second inductor pattern is formed on the first inductor pattern and electrically connected thereto, and the third inductor pattern is formed on the second inductor pattern and electrically connected thereto, wherein the first inductor pattern, the second inductor pattern, and the third inductor pattern have similar pattern. Because the thickness of the inductor can be increased by forming a multi-layer inductor structure, the resistance of the inductor, therefore, is reduced.

  • Publication number: 20060253723
    Abstract: A semiconductor memory employs the redundancy memory technique and the error correction code technique and method of correcting errors. The method of correcting errors reads data bits and a checking bit from a predetermined unit of a first memory array such as a main memory array, and the data bits are checked based on the checking bit to determine if there is any error. If there is an error in the data bits, the checking bit is used to correct the error and the data bits together with the checking bit are written back to the predetermined unit. If there is still error in the data bits after the read-check-write process is repeated a predetermined number of times, the predetermined unit is marked as a faulty unit and the data bits together with the checking bit are written to a second memory array such as a redundancy memory array.

  • Patent number: 7117409
    Abstract: In a method of testing a multi-port memory in accordance with a test pattern, test clock signals having the same test clock frequency but with different delay periods introduced therein are generated for controlling memory access through the different access ports of the memory. Consecutive memory operations of a test element of the test pattern are then conducted in a folded sequence upon a memory cell through the different access ports in accordance with the test clock signals such that the memory operations are completed within the same test clock cycle of the test element.

  • Patent number: 7049240
    Abstract: A method for forming a SiGe HBT, which combines a SEG and Non-SEG growth, is disclosed. The SiGe base layer is deposited by a Non-SEG method. Then, the first-emitter layer is developed directly upon the SiGe base layer that has a good interface quality between the base-emitter. Next, a second poly silicon layer, which has a dopant concentration range within 1E19 to 1E21 (atom/cc), is deposited by SEG method. It not only reduces the resistance of the SiGe base layer, but also avoids the annealing that may influence the performance of the device.
